Abstract
In this study, we investigate the radiative and semileptonic decays of doubly heavy baryons (DHBs) within the framework of the Hypercentral Constituent Quark Model (HCQM). Our focus is on determining static and dynamic properties such as ground-state masses, magnetic moment, transition magnetic moment, radiative decay and heavy-to-heavy semileptonic decay rates, including their corresponding branching fractions. The ground-state masses are calculated using the six-dimensional hyper-radial Schrödinger equation. The magnetic moments and transition magnetic moments for \(J^P=\frac{1}{2}^+\) and \(J^P=\frac{3}{2}^+\) baryons are also calculated. In addition, radiative decay widths are computed from the transition magnetic moment. We employed the Isgur-Wise function (IWF) to analyse the semileptonic decay widths of DHBs. The obtained results are compared with other theoretical predictions.
期刊介绍:
International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
